Freeman Dyson, an award-winning British scientist and retired professor of physics at the Institute for Advanced Study, said that the science on climate change isn’t “at all clear,” and in fact, humans are actually helping the planet. […]

“Well, what I would like to emphasize is that human actions have very large effects on the ecology which have nothing to do with climate. Carbon dioxide is what we’re producing in big quantities and putting into the atmosphere,” Dyson said. “It happens to be a very good fertilizer for all kinds of vegetation, good for wildlife, good for agricultural production.

“So it has many benefits,” Dyson said, “and this is something you have together with the climate effects, which are much less certain. So it’s a question of drawing a balance. I'm just saying I don’t understand it, and neither does anybody else.

“I'm skeptical, because I don't think the science is at all clear, and unfortunately, a lot of the experts really believe they understand it and maybe have the wrong answer,” Dyson said. …
